Abstract
A kind of high-precision pressure actuator, including capsule stacks, valve assembly, pressure inlet, valve element, valve body, pressure inlet, O cushion rubber, nut, lower spring cup, sleeve, spring, upper spring seat, adjusting screw, back-up ring, pad, fluoroplastic ring, pressing plate, pressure inlet, packing ring and nut；The porch of described pressure regulator connects gas cylinder pressurization gas, exit connects tank pressure piping；It is characterized in that being provided with feedback cavity on described valve body, using tank pneumatic die cushion pressure as feedback signal, adjusting restriction aperture, being tightly connected by fluoroplastic ring between described pressure regulator entrance and feedback cavity.Instant invention overcomes pressure regulator adjusts that sensitivity is not high and the less problem of the adjustable nargin of working flow in prior art, substantially increase the degree of regulation of pressure regulator.
Description
Technical field
The present invention relates to a kind of pressure regulator, more particularly to a kind of aerospace craft liquid propellant tank supercharging gas
Road high-precision pressure actuator.
Background technology
In aerospace craft field, existing pressure regulator adopts outlet pressure as feedback signal, adjusts restriction
Aperture, controls outlet pressure, by outlet pressure indirect control tank boost pressure.
Using the piston with O cushion rubber or diaphragm as pressure element and potted component more than existing pressure regulator, by
Selecting rubber in the O cushion rubber material, O cushion rubber frictional force is larger, have impact on the working sensitivity of whole product to a certain extent more；And
Diaphragm its travel is less, thus leading to the adjustable nargin of whole working flow less.
Content of the invention
The primary and foremost purpose of the present invention is that and overcomes the shortcomings of existing for existing pressure regulator, thus providing a kind of height
Precision pressure actuator.
The high-precision pressure actuator of the present invention includes：Capsule stacks, valve assembly, pressure inlet, valve element, valve body, adapter
Mouth, O cushion rubber, nut, lower spring cup, sleeve, spring, upper spring seat, adjusting screw, back-up ring, pad, potted component, pressing plate, connect
Ozzle, packing ring, nut.Pressure regulator entrance connects gas cylinder pressurization gas, outlet connects tank pressure piping, feedback port connects tank gas
Pillow gas.
Pressure inlet 3, pressure inlet 6 and pressure inlet 18 are separately fixed on valve body 5, and valve element 4, pressing plate 17 and potted component 16 are solid
It is scheduled in valve body 5, valve element 4 is sequentially connected nut 8, back-up ring 14, O cushion rubber 7 and capsule stacks 1, valve element 4 other end is sequentially connected
Valve assembly 2, packing ring 19 and nut 20, described capsule stacks 1, pad 15 and sleeve 10 are fixed on valve body 5 left end, lower spring cup
9 are sequentially connected spring 11, upper spring seat 12 and adjusting screw 13, and four are contained in sleeve 10 jointly.
Described pressure regulator is provided with feedback cavity on valve body, and feedback port connects tank pneumatic die cushion pressure, using tank pneumatic die cushion
Pressure, as feedback signal, adjusts restriction aperture, directly controls tank boost pressure；
Potted component between described entrance and feedback cavity adopts fluoroplastic ring；
Using capsule stacks as pressure element and executive component.
Described high-precision pressure actuator passes through to arrange feedback cavity, and feedback port directly connects tank pneumatic die cushion pressure, controls tank
Boost pressure；Capsule stacks rigidity is little, effective area big, improves tank boost pressure precision, increases restriction and adjusts model
Enclose, improve the adjustable nargin of working flow.
